- Burning fat and carbohydrate during exercise
06-18-2007 · EurekAlert!
In a paper published in the Journal of Physiology, Helge, Stallknecht, Richter, Galbo, and Keins from Copenhagen shed light on fat oxidation during exercise and physical activity. Their observations suggest that fat oxidation during exercise reflects a fine interplay between the cardiovascular, neurological, endocrine and muscle metabolic systems.

- Polymer opal films shed new kind of light on nature
07-23-2007 · EurekAlert!
Imagine cleaning out your refrigerator and being able to tell at a glance whether perishable food items have spoiled, because the packaging has changed color, or being able to tell if your dollar bill is counterfeit by stretching it to see if it changes hue. These are two commercial applications for a new type of flexible plastic film, developed by scientists at the University of Southampton in the United Kingdom and Darmstadt in Germany.

- NIST develops rapid method for judging nanotube purity
02-01-2007 · EurekAlert!
Researchers at NIST have developed a sensitive new method for rapidly assessing the quality of carbon nanotubes. Initial feasibility tests show that the method not only is faster than the standard analytic technique, but also effectively screens much smaller samples for purity and consistency and better detects sample variability.

- Strontium atomic clock demonstrates super-fine 'ticks'
11-30-2006 · EurekAlert!
Using an ultra-stable laser to manipulate strontium atoms trapped in a "lattice" made of light, scientists at JILA (a joint institute of NIST and the University of Colorado at Boulder) have demonstrated the capability to produce the most precise "ticks" ever recorded in an optical atomic clock—techniques that may be useful in time keeping, precision measurements of high frequencies, and quantum computers using neutral atoms as bits of information.
